Which of the following types of microscope is used to study the internal structures of a cell?
Correct answer: D. Electron microscope
- A. Simple microscope
- B. Compound microscope
- C. Light microscope
- D. Electron microscope
Explanation
An electron microscope uses a beam of electrons instead of visible light to image the specimen, providing much higher magnification and resolution than light microscopes. It is capable of resolving the ultrastructure and internal organelles of cells with precise details. Electron microscopes come in two main types: transmission electron microscope (TEM) and scanning electron microscope (SEM). Hence, option D is the best choice.
